A/T Mode allows you to choose how automatic transmission behaves in selecting "overdrive mode" which gives you fuel economy when you do not need maximum power due to easy road conditions.
There are three positions, POWER,
AUTO and HOLD.
POWER: when switched on, the
POWER light will show on the dash. In normal driving, with the shift lever in
D, the power mode will operate through the full range of gears 1 to 3 plus
overdrive when active. In 2, the power mode will only operate through 1
to 2, and in L, the power mode will only operate on the first gear.
AUTO: In auto mode, the transmission
will automatically change between POWER and ECONOMY modes as driving conditions
define, changing to POWER mode for example when starting a hill ascent.
HOLD: The HOLD light will show on
the dash. The transmission will operate in ECONOMY mode through the full
range of selected gears, not changing any higher than the selected gear, for
example if you have selected L, the transmission will not change up to 2 or
higher. (If dashboard indicators are not lighting up due to fuses bulbs or electrical problems, you can still use the setting: rear side of the button pressed down= HOLD, Front Side of button is pressed down = POWER, Middle Position = AUTO)
